BUPIVACAINE HYDROCHLORIDE PRESERVATIVE FREE vs CYCLAINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bupivacaine blocks voltage-gated sodium channels on neuronal membranes, inhibiting the propagation of action potentials and resulting in local anesthesia.
Cyclaine is a local anesthetic that reversibly blocks nerve conduction by decreasing the permeability of the neuronal membrane to sodium ions, thereby stabilizing the membrane and preventing the initiation and transmission of electrical impulses.
0.25-0.5% solution, up to 2 mg/kg (max 150 mg) per dose via infiltration, peripheral nerve block, or epidural; may repeat every 3-6 hours as needed. For epidural: 0.5% solution, 15-20 mL for surgical anesthesia.
0.2–0.4 mg/kg IV for induction; 0.5–1.5 mg/kg/h IV infusion for maintenance.

Terminal elimination half-life is 2.7 hours (range 1.5-5.5 hours). Prolonged up to 8-10 hours in neonates and 24-48 hours in severe hepatic impairment.
Terminal elimination half-life: 2-4 hours in adults; prolonged with hepatic impairment.
Renal excretion accounts for approximately 95% of the dose, with about 50% excreted unchanged. The remainder is primarily hepatic metabolism followed by renal elimination of metabolites. Biliary/fecal excretion is minimal (<5%).
Renal: minimal (<5% unchanged); biliary/fecal: >70% as metabolites; small amount exhaled as CO2.
